The gpuflag and gpunum settings in the pair_style command refer to how the GPUs on your system are configured.
-Set gpuflag to one/node if you have multiple gpus on 1 CPU node of -your system. In this case, gpunum should be the starting GPU ID. +
Set gpuflag to one/node if you have a single compute "node" on +your system, which may have multiple cores and/or GPUs. Gpunum +should be set to the ID of the (first) GPU you wish to use with LAMMPS +(another GPU might be driving your display).
-Set gpuflag to one/node if you have multiple gpus on 1 node -of your system. In this case, gpunum should be the starting GPU ID. +
Set gpuflag to one/gpu if you have multiple compute "nodes" on +your system, with one GPU per node. Gpunum should be set to the ID +of the GPU.
-// set multi_gpu_mode to one/gpu to select the same gpu id on every node - // -- param is id of gpu - // set multi_gpu_mode to multi/gpu to get ma - // -- param is number of gpus per node +
Set gpuflag to multi/gpu if you have multiple compute "nodes" on +your system, each with multiple GPUs. Gpunum should be set to the +number of GPUs per node. +
